Homework from 10-21 and 10-22

Hello!

We had a quiz on names and symbols today for elements. If you missed this, make it up ASAP because it is close to the end of the quarter.

We also did the penny lab - this will take you about 30 minutes to do, and as long as your partner completed it in class, you will probably use their data for the lab report.

The only homework was to complete page 90 (which was assigned last class), complete the Separation of Mixtures lab report (again, assigned last class, for everyone except B1), and study for another name/symbol quiz. Nothing new.

We will discuss the lab report for the penny lab when we have our next class.

Enjoy the nice weather before we go back to cold and rainy!

Homework from 10-19 and 10-20

Hi everyone!

 

In class today, we did some practice problems for dimensional analysis first, to try to refresh everyone on how to do them. We then did a practice quiz on the names and symbols for elements in order to get everyone to know what the quizzes over the next couple of classes would be like.

 

After that, we discussed the lab report requirements for the lab that all of my classes except B1 did, so this section doesn't apply to them. All I asked for was a neatly written or typed report, one per person (not one per group), answering the following questions. The first is to try to figure out the percentages of the iron, sand, and salt that were in the mixture. If you are unable to do this for some reason, indicate why. The second question is an error analysis. In several paragraphs (do a good job with this!) explain what problems you had with the lab and how you could do better if we had to do this again. Since everyone had problems with it, I expect a good explanation from each of you! This is due on Friday (10/23) or Monday (10/26), depending on when you have me for class. Again, B1 doesn't have to do one because we didn't do the lab due to our standardized test day last Wednesday.

 

The next thing we did was talk about the Penny lab, which we are doing Wednesday and Thursday of this week. You received a packet which contains the lab, and directions for making the data table which you need for next class. I explained that the only requirements for the data table are legible and functional - you need to be able to use it to record the data for the lab - it doesn't need to be typed. This is due next class because this is when you need it, and only one per group is needed.

 

Finally, we went through lesson 14, which has a bunch of introductory information for atomic theory history.

 

Homework:

 

Page 90 - this is due 10-23 or 10-26.

Data table for Penny Lab - due 10-21 or 10-22

Quiz on Names and Symbols - happening the next couple of classes - so study!

Lab report for Separation of Mixtures lab - one per person, due 10-23 or 10-26.

 

Have a great day, and enjoy the nicer weather we seem to be having before the depths of winter set in (like last week)!

Homework for Thursday/Friday 10-15 and 10-16

There is no written homework for this time because we took a test both days. Students should have finished up the labs they were working on - we will talk about the lab report on Monday and Tuesday. Also, you should start memorizing names and symbols for the following elements:

 

1-20 (Hydrogen, Helium, Lithium, etc... up to Calcium - the first 20 Atomic Numbers)

Cr, Mn, Fe, Ni, Cu, Zn, Br, W, Ag, Sn, I, Pt, Au, Hg, Pb

 

There will be quizzes given starting Wesnesday and Thursday of next week on these - all you need to know are names and symbols - for example, I will say O and the students will need to write oxygen, or I will say Silver and the students will need to write Ag.

 

Also, rewrites for any lab reports which were handed back over the last couple of days need to be turned in within a week or so - if you're not sure how to fix whatever was wrong, see me!

 

Have a good weekend!

Oops sorry!

The boxes below the last homework post are from my email signature file - they are stats for a game I play. I didn't intend to post them, just forgot to remove them before I clicked "send" on the email. That's why they're there - sorry!

Homework for 10/2 and 10/5

Hi everyone!

 

Homework for 10-2 and 10-5 is to finish page 70, because it is something that B day students were assigned before and A day students are receiving as an assignment today. Vocabulary is due 10/6 and 10/7 as well.

 

On a side note, don't forget to get your chicken toss rosters in if you plan to participate after the beach walk - those are due back to me on Wednesday, Oct 7, at the latest.

 

Thanks! Have a great weekend!
